The victim was walking on the sidewalk in the Marigny and appears to be looking at his cellphone. In the video a man with a gun can be seen sneaking up behind him. The attacker turns the man around, points the shotgun at his face and tells him to give up his money.

The victim disarms the would be robber with a few quick moves then chases him off. Police said moments later a car rolled up to the man and the driver told him to give the gun back in exchange for the cellphone that he'd dropped. Instead the man shattered the back windshield of the car with the shotgun.

It's a surprising scene that serves as a reminder to Marigny residents.

"Even though I know that it's all around me, I feel like 'well, it hasn't happened to me,' but it just reminds you that it's very common and to be very careful," said Glynis Rumsey.

With violent crimes on the rise in the Marigny, residents are taking action to catch the criminals and ward off future attacks.

"The neighbors and I got together and put in a seven-camera system that wraps around the block," said Todd Paden, who's lived in the Marigny 27 years.

"It makes us feel safer. At least we can see what's going on. I don't know if we've actually caught anyone yet, but we've given it to police. They now call me when something happens," he said.

Two teenagers were arrested last month after a Marigny beating was caught on camera. Surveillance cameras caught another armed robber in the act Friday. In that video are faint images of a victim running away from the attacker.

"He got away, probably very scared, and then when I saw this guy the next night it was like 'wow, that's how it always should be," said Gary Feindel who provided police with video of the latest attack.

Rumsey said she is very impressed with the victim's response. "I think you never know how you're going to react in that situation either have that fight or flight response. That guy obviously had the fight response, and it worked out in his favor thank goodness."

Though it's impressive, police don't encourage responding this way. They advise if your life is in danger, the best thing to do is comply by giving perpetrator your wallet or whatever they are requesting then get away as easily and quickly as possibly.

Police are trying to find out if the man in the video had prior military training, but said judging by the maneuver he used to defend himself he appears to have some type of training.
